ONE of the UK's top police officers today asked supermodel Kate Moss to return home and answer questions over her alleged cocaine use.

Metropolitan Police Assistant Commissioner Tarique Ghaffur said he wanted Moss to tell police "her side of the story".

In an interview with The Sun he said: "For everybody's sake, and for her to move on, the sooner she speaks to us the better.

"We wish for the investigation to take its course, and she would be dealt with very fairly and proportionately, as would be the case with anybody else."

Moss, 31, has been dogged by questions over her alleged cocaine use after being caught on camera apparently using the class A drug in a west London music studio.

The studio was being used at that time by her ex-boyfriend Pete Doherty, troubled frontman of rock group Babyshambles.

She has since been in rehab in Arizona and was pictured earlier this week skiing in Aspen, Colorado. She is now thought to be making plans to settle in Los Angeles with her three-year-old daughter Lila Grace.

Mr Ghaffur, who is responsible for the specialist crime directorate, said police will not formally request her extradition or send officers to the United States.

Arrests

He said: "What I can say, on behalf of the investigation, is that the net on others involved is closing in, and there will be arrests.

"What we have done so far is conducted searches of the studios where the matter was filmed, in addition to obtaining the full digital recording of the incident, which is currently being closely studied by the investigative team.

"Our position, in relation to how we deal with drugs in this sort of environment, has been made very clear in Sir Ian Blair's comments when he became Commissioner.

"He made it very clear that we would not only deal with drug takers and suppliers at street level or community levels, but we would also look at what has been termed as middle class or upper class drug users".

Mr Ghaffur said the investigation is progressing "extremely well", and investigators are in touch with representatives of Moss.

He added that although no arrests have been made, the case is not being dealt with in isolation, and evidence is being gathered on the criminal networks involved.

It is understood that Moss would not suddenly be arrested, but rather interviewed under caution by appointment.

A file will then be submitted to the Crown Prosecution Service who will decide whether to prosecute any of the people involved.
